1) SONET ring with four stations. Suppose tributaries established between each pair of stations to produce logical topology. Find capacity required in each hop of SONET ring in following three cases assuming first ring is unidirectional and then that ring is bidirectional
a) Traffic between each pair of stations is STS-1
2) Calculate number of voice channels that can be carried by STS-1. Calculate number of MPEG2 video channels that can be carried by these systems?
Please show how steps for the calculation.
With your assistance, I will be able to complete the remaining parts of the questions.
